[0050] See also Figures 1 to 3 The hydraulic gate hoist generally consists of a hydraulic station, a hydraulic cylinder, a hydraulic circuit and a related electrical control system, and is often used for the opening and closing operation of the gate 100. The safety and reliability of its operation are of great significance. The hydraulic gate hoist has a complex mechanism, involving multiple technical fields such as hydraulics, machinery, electrical appliances, and structure, and has a very strong specificity. Its daily maintenance and fault inspection and repair have very high requirements for technicians, and it is often located in remote areas, making it difficult for technical service personnel to respond quickly on site.

[0051] At present, the operation monitoring, fault repair and daily maintenance control of hydraulic gate hoists are generally carried out manually:

[0052] Operation monitoring: When the equipment is running, it has current detection information. When the equipment stops running, there is no past information to query;

[0053] Fault repair: Manual inspection and repair are only carried out when the equipment is damaged or cannot work normally. This method has a long equipment downtime, high requirements for on-site operators, and high maintenance costs;

[0054] Maintenance control: Daily maintenance and operation control of equipment is carried out manually by referring to the manual. The steps are cumbersome, the requirements for users are high, and mistakes are easy to occur. This method is easy to cause maintenance waste and even cause hidden dangers of failure during the maintenance process.

[0055] In one invention, the hardware layer includes oil cylinders, hydraulic stations, hydraulic circuits, sensors, electrical control systems, central control machines, upper monitoring machines, and portable devices.

[0056] In one invention, by obtaining signals of the working status of various components of the system from sensors arranged at various positions of the hydraulic gate hoist, including motor speed, solenoid valve position, pressure, flow, temperature at various positions of the hydraulic oil circuit, displacement, speed of various moving parts of the cylinder and gate, voltage and current of the electrical system, the system transmits all data to the central control computer for real-time display on the screen and writes into a log.

[0057] The intelligent system of the central control machine determines the working condition of the system by analyzing the real-time data and logs, and converts the operation instructions into control signals and sends them to the control cabinet, and then adjusts the control signals through the information fed back by the data to finally meet the operation requirements. When the sensor data exceeds the set limit or the deviation from the daily historical data exceeds the threshold, the central control machine system will give a warning message, and compare the sensor data and operation log data with the database to determine the location of the abnormal state, possible fault components and types, and further provide solution prompts. During the operation of the system, the central control machine transmits the relevant data and prompt information to the upper monitoring machine through the Internet or dedicated data lines, and transmits the data and prompt information to the portable device through the wireless network, including sending it to the mobile phone in the form of text messages.

[0062] Abnormal operation warning: By analyzing the sensor information log, the fault trend can be discovered, the fault can be foreseen in advance and warnings can be provided.

[0063] Remote status monitoring: The superior department or superior leadership unit can view the working status and operation status of the system in real time through the Internet or dedicated data lines through the host computer;

[0069] Sensor signal log: The system archives all sensor information in log form for analysis;

[0070] Operation log: The system archives all operation information in log form for analysis;

[0071] Alarm information log: The system archives all alarm information and prompts in log format for analysis;

[0072] Life reminder for wearing parts: The system makes statistical analysis on the actual working time of the equipment and counts the life of wearing parts that need to be replaced. When the life of the hydraulic gate hoist operation and maintenance intelligent service platform is approaching, the system prompts for spare parts, and when the life cycle is reached, the system prompts for replacement. The life information of this system based on the actual working conditions is more in line with the actual design of the hydraulic gate hoist operation and maintenance intelligent service platform, avoiding failures and waste caused by the past extensive management;

[0073] Maintenance plan reminder: The system provides maintenance reminders in a timely manner according to the maintenance plan of the design unit;

[0074] Usage status analysis: The system conducts statistical analysis on the actual usage status of the equipment and provides better operation and maintenance solutions. It can also provide a balancing solution for the workload and time of multiple devices in the large-area hydraulic gate hoist operation and maintenance intelligent service platform;

[0075] Fault trend analysis: The system conducts statistical analysis on the occurrence of faults and misoperations, discovers patterns and trends, and provides report information;

[0076] Abnormal operation prompt: The system automatically detects and prompts abnormal operations that do not meet the conditions through statistical learning of past operation information;

[0077] Fault diagnosis learning: The system provides continuously growing intelligent diagnostic functions through statistical learning of past fault information, current parameters, and solutions, and adapts to the specific problems of individual projects.

[0078] In one invention, an overall intelligent and digital hydraulic gate hoist is provided to ensure automatic control of operation, full-time monitoring of the working status, remote intelligent diagnosis of faults and abnormal operations by the hydraulic gate hoist operation and maintenance intelligent service platform, and intelligent guarantee of normal operation.

[0079] For example, in one invention, the steps for discovering and handling oil contamination are as follows:

[0080] During operation, the oil resistance and oil transparency sensors provide real-time feedback on the oil conductivity and oil transmittance data. When the conductivity exceeds the set threshold of the hydraulic gate hoist operation and maintenance intelligent service platform and the transmittance is lower than the set threshold, the central control system will give an oil contamination alarm and prompt you to check and replace the oil. The warning information will be sent to the upper monitoring machine and portable devices of the hydraulic gate hoist operation and maintenance intelligent service platform, and a situation report will be sent by SMS to the set mobile phone number.

[0081] When only the conductivity exceeds the set threshold, the central control machine system analyzes the historical data log. If the recent conductivity data shows a continuous upward trend, the central control machine system of the hydraulic gate hoist operation and maintenance intelligent service platform will give an oil contamination alarm and prompt to check and replace the oil, and send the warning information to the upper monitoring machine and portable devices, and send a text message of the situation briefing to the set mobile phone number; if there is no definite trend in the conductivity of the historical log and the subsequent conductivity data is lower than the threshold, the system will give a prompt to check the oil condition, and send the prompt information to the upper monitoring machine and portable devices, and send a text message of the situation briefing to the set mobile phone number; if there is no definite trend in the conductivity of the historical log and the subsequent conductivity data continues to be higher than the threshold, the system will give a prompt to check the oil resistance sensor condition, and send the prompt information to the upper monitoring machine and portable devices, and send a text message of the situation briefing to the set mobile phone number.

[0082] When the transmittance is lower than the set threshold, the control system analyzes the historical data log. If the recent transmittance data shows a continuous downward trend, the central control system of the hydraulic gate hoist operation and maintenance intelligent service platform will give an oil contamination alarm and prompt to check and replace the oil, and send the warning information to the upper monitoring machine and portable devices. At the same time, the situation briefing will be sent to the set mobile phone number by SMS. If there is no definite trend in the transmittance of the historical log and the subsequent transmittance data is higher than the threshold, the system will give a prompt to check the oil condition, and send the prompt information to the upper monitoring machine and portable devices, and send the situation briefing to the set mobile phone number by SMS; if there is no definite trend in the transmittance of the historical log and the subsequent transmittance data continues to be lower than the threshold, the system will give a prompt to check the oil transparency sensor condition, and send the prompt information to the upper monitoring machine and portable devices, and send the situation briefing to the set mobile phone number by SMS.

[0083] For example, in one invention, the automatic deviation correction control of the gate during installation, commissioning and maintenance is as follows:

[0084] Select automatic gate correction on the on-site portable control device, the system checks the cylinder stroke position data, controls all cylinders to move synchronously to the extended state of the semi-hydraulic gate hoist operation and maintenance intelligent service platform; the system checks the gate level sensor data, determines the deviation on both sides according to the sensor data, and slowly lifts the low-side cylinder until the sensor provides the water hydraulic gate hoist operation and maintenance intelligent service platform level data; gives a prompt that the gate correction is in place and waits for confirmation. After confirmation, set the stroke position of the cylinders on both sides to be synchronously bound.

[0085] Specifically, many sensors are installed in the hydraulic gate hoist equipment. After the equipment has been put into operation for a certain period of time, it can monitor various data of the equipment, analyze the health of the equipment in the background, and push necessary maintenance information to customers. Through the alarm sensors installed in the wearing parts, it can accurately determine and remind customers of the wearing parts that need maintenance. For example, when the alarm set in the filter is blocked, the customer can be accurately prompted to replace the filter element of the equipment. Or after the equipment is put into operation, the maintenance information such as the need to replace the hydraulic oil can be pushed to the customer through the analysis software based on the motor operation time and frequency, as well as the total operation time of the equipment. And so on. This automatic judgment and reminder of maintenance can facilitate better operation of the equipment, prevent equipment failures before they happen, extend the service life of the equipment, and reduce the losses caused to customers by equipment downtime due to maintenance.

[0086] See also Figures 4 to 7 For example, the present invention provides an intelligent service platform for the operation and maintenance of a hydraulic gate hoist. The intelligent service platform for the operation and maintenance of a hydraulic gate hoist includes a central control machine and a hydraulic gate hoist. The hydraulic gate hoist is provided with an oil resistance sensor, an oil transparency sensor, a motor speed sensor, a solenoid valve position sensor, an oil circuit pressure sensor, an oil circuit flow sensor, an oil circuit temperature sensor, a piston displacement sensor, and a piston speed sensor.

[0087] In one embodiment, a maintenance box cover 21 is provided on the main body of the hydraulic station, a groove 211 is provided on the side wall of the maintenance box cover 21, two hook ring groups 212 are provided on the top of the maintenance box cover 21, each of the hook ring groups 212 includes two hook rings and a rectangular beam 213 connected to the two hook rings, a maintenance parameter display screen 214 is provided in the groove 211, and the maintenance parameter display screen 214 is wirelessly connected to the central control machine, and a sealing plate 215 is also provided on the edge of the groove 211, and the sealing plate 215 is rotatably arranged on the maintenance box cover 21 The surface of the maintenance parameter display screen 214 is blocked and sealed, and the edge of the sealing plate 215 is provided with an elastic arch strip 216, and the elastic arch strip 216 is against the edge of the groove 211, and the elastic arch strip 216 has a cylindrical edge 217, and a dehumidification channel 2175 is formed in the cylindrical edge 217, and the opposite ends of the dehumidification channel 2175 are respectively connected to two drainage grooves 2178, and the two drainage grooves 2178 are both recessed on the maintenance box cover 21, and the distance between the two drainage grooves 2178 gradually increases in the direction toward the ground.

[0088] Since the hydraulic gate hoist is provided with an oil resistance sensor, an oil transparency sensor, a motor speed sensor, a solenoid valve position sensor, an oil circuit pressure sensor, an oil circuit flow sensor, an oil circuit temperature sensor, a piston displacement sensor and a piston speed sensor, the central control machine is electrically connected to the above-mentioned multiple sensors. Therefore, the central control machine can be used to remotely diagnose the fault of the hydraulic gate hoist according to various parameters, and send maintenance information to the handheld device, so that the user or maintenance personnel can timely know the various damage states of the hydraulic gate hoist, so as to facilitate timely maintenance. Moreover, the maintenance parameter display screen 214 on the maintenance box cover 21 is also convenient for the staff at the oil station to know the situation of the hydraulic station 20, so as to facilitate the maintenance of the hydraulic station 20. The maintenance box cover 21 is conducive to dust and water prevention. Through the dehumidification channel 2175, rainwater or moisture can flow down along the drain trough 2178 in daily work without affecting the maintenance parameter display screen 214. The elastic arch strip 216 and the cylindrical edge 217 are conducive to the sealing of the sealing plate 215.

[0089] For example, in order to facilitate the control of the opening and closing of the gate, the oil cylinder 30 includes a cylinder shell, a piston and a piston rod, the piston is slidably arranged in the cylinder shell, and the piston rod is connected to the piston. The oil cylinder 30 also includes a hanging head, which is located outside the cylinder shell and connected to the piston rod. The cylinder shell includes a main cylinder body, a front cylinder cover and a rear cylinder cover, and the front cylinder cover and the rear cylinder cover are respectively arranged at the front and rear ends of the main cylinder body. One end of the piston rod away from the piston protrudes outside the front cylinder cover, and the hanging head is coaxially connected to the end of the piston rod. An oil inlet pipe is also arranged on the side wall of the front cylinder cover, and the oil inlet pipe is connected to the front cylinder cover through a one-way valve. The diameter of the oil inlet pipe is smaller than the inner diameter of the main cylinder body, and a buffer structure is arranged in the oil inlet pipe. A cylinder bracket is arranged on the side wall of the gate pier, and the cylinder bracket is supported at the bottom of the side wall of the main cylinder body. The oil cylinder bracket is fixed to the gate pier by a plurality of anchor screws. The oil cylinder bracket is provided with a plurality of buffer pads, which surround and form a semicircular groove, and the side wall of the main cylinder body is accommodated in the semicircular groove. The main cylinder body is also provided with an observation port, and a transparent observation plate is provided in the observation port. By providing the oil cylinder bracket, the operation stability of the oil cylinder 30 is improved, thereby improving the operational stability of the gate opening and closing.

[0090] For example, sometimes, the sealing plate 215 and the cylindrical edge are used to seal the groove 211 to protect the maintenance parameter display screen 214. When maintenance or inspection is required and viewing is required, the sealing plate 215 needs to be opened for viewing. The cylindrical edge 217 is provided with a crack 2174, and the crack 2174 is away from the maintenance parameter display screen 214. The crack 2174 is connected to the dehumidification channel 2175. Two sleeves 22 are arranged on the top of the side wall of the maintenance box cover 21. The two sleeves 22 are arranged opposite to each other. A latch rod 23 is arranged in each sleeve 22. An elastic pull rope 235 is arranged between the two latch rods 23, and a stop block 236 is arranged at the end of each latch rod 23. For example, when the maintenance parameter display screen 214 is opened, the sealing plate 215 is used to be flipped and attached to the side wall of the maintenance box cover 21, the two latch rods 23 are inserted into the opposite ends of the dehumidification channel 2175, and the elastic pull rope 235 is used to enter the dehumidification channel 2175 from the crack 2174 to fix the sealing plate 215.

[0091] For example, when the sealing plate 215 is released, one side of the blocking block 236 of the latch rod 23 is protruded at the corner of the maintenance box cover 21, and the two blocking blocks 236 are respectively blocked on the opposite sides of the maintenance box cover 21 to hold the elastic pull rope 235. The holding and positioning of the two blocking blocks 236 can ensure the stability of the elastic pull rope 235, and the sealing plate 215 can also be automatically positioned by pulling the two blocking blocks 236. When the sealing plate 215 is clamped, the blocking blocks 236 are rotated so that the blocking blocks 236 can move toward each other to the same side wall until the two blocking blocks 236 are respectively blocked on the two sleeves 22, thereby completing the positioning.

[0092] For example, a triangular cover 28 is provided on the top of the maintenance box cover 21, wherein one of the sleeves 22 is provided on the triangular cover 28, wherein the end of the other sleeve 22 is aligned with the oblique edge of the bottom of the triangular cover 28. When the triangular cover 28 is rotated to open, the elastic drawstring 235 is used to maintain the tension to ensure the smooth operation of the triangular cover 28, and the triangular cover 28 can overcome the elastic drawstring 235 to open. When closed, the elastic drawstring 235 can pull the triangular cover 28 to stably position it on the top of the maintenance box cover 21.

[0093] For example, a cover box 29 is convexly provided on one side of the maintenance box cover 21, and the cover box 29 is covered on the motor 201. A maintenance tool box 291 is rotatably provided on the side wall of the cover box 29, and a variety of repair tools are installed in the maintenance tool box 291. The maintenance tool box 291 includes a box body 292 and a cover plate 293 slidably provided on the box body 292, and the box body 292 is provided with a slide groove 294 on opposite sides, and the cover plate 293 is respectively inserted into the two slide grooves 294 on opposite sides.
